Two civil rights advocates -- including prominent attorney Norman Siegel, who ran against de Blasio for public advocate in 2009 -- apparently think so.

Michael Meyers, executive director of the New York Civil Rights Coalition, who is African American, and Siegel, a civil rights attorney and former executive director of the New York Civil Liberties Union, who is Caucasian, in a press release, said they faxed a letter of protest Saturday morning to Mayor de Blasio.

Attempts to reach the mayor's office for response Saturday were unsuccessful.

All 11 of the invited clergy and community leaders were black, Meyers and Siegel noted, including three representatives of the National Action Network, led by the Rev. Al Sharpton; Sharpton's close associate, the Rev. Herbert Daughtry, and City Councilwoman Debi Rose (D-North Shore), the only City Council member invited to the sit-down, which was called in the aftermath of the July 17 death of Port Richmond resident Eric Garner at the hands of police.

Excerpts from the Meyers-Siegel letter, which was attached to the release said, in part:

"...This city does not need what amounted to a 'one race' summit on black victims of police abuse, when victims of police misconduct come in various colors, shapes and sizes, and include blacks, Asians, Hispanics, and whites, as well as people of different sexual identities...Where were the Latinos? The whites? The Asians? And all the other identifiable groups that have expertise and relevant experiences in this field?"

The Meyers-Siegel letter scolded de Blasio with other questions such as, "Were you not elected to be the Mayor of all the people? Or do you believe -- as it appears -- that because Eric Garner is black, that only blacks are upset with his death by chokehold?"
